REMOTE SENSOR (THGR122NX)

REMOTE SENSOR (THGR122NX)

This product is shipped with a THGR122NX Thermo / Hygro
Sensor that collects Temperature and Humidity data. Data
can be collected from up to 3 sensors. Additional sensors sold
separately.

SET UP SENSOR

1. Open the remote sensor battery compartment with a
small Phillips screwdriver.

2. Insert the batteries, matching the polarity (+ and -) as
shown in the battery compartment.

CLOCK

The clock automatically synchronizes the current time and
date when it is brought within range of the WWVB-60 atomic
clock signal generated from Fort Collins, Colorado. For more
information, please visit: www.boulder.nist.gov/timefreq/sta­tions/>radioclocks.htm

NOTE The signals are collected by the main unit when it is
within 1500 km (932 miles) of a signal.

Initial reception takes 2-10 minutes, and is initiated when you
first set up the unit, and whenever you press RESET. If the RF
signal is weak, it can take up to 24 hours to get a valid RF
signal reception. Once complete, the reception icon will stop
blinking. The icon is shown in the Clock Area.

For best results:

• Insert the batteries and select the channel before you
mount the sensor.

• Place the sensor out of direct sunlight and moisture.

• Do not place the sensor more than 98 feet (30 meters) from
the main (indoor) unit.

• Position the sensor so that it faces the main (indoor) unit,
minimizing obstructions such as doors, walls, and furniture.

• Place the sensor in a location with a clear view to the sky,
away from metallic or electronic objects.

• Position the sensor close to the main unit during cold
winter months as below-freezing temperatures may affect
battery performance and signal transmission.

Standard Alkaline batteries contain significant amounts of
water. Because of this they will freeze in low temperatures of
approximately 10°F (-12°C). Disposable Lithium batteries
have a much lower threshold for temperature with an estimated
freezing range of below -40°F (-40°C).

Wireless ranges can be impacted by a variety of factors such
as extremely cold temperatures. Extreme cold may temporarily
reduce the effective range between the sensor and the base
station. If the unit's performance fails due to low temperature,
the unit will resume proper functioning as the temperature
rises to within the normal temperature range (i.e. no permanent
damage will occur to the unit due to low temperatures). The
Liquid Crystal Display in outdoor thermometers will remain
operational to -20°F (-7°C) with adequate power.

You may need to experiment with various locations to get the
best results.
